Data Analysis

1. Type of data analysis conducted depends on how your variables are measured. If your independent variable is:

   • Categorical / Nominal
     • and if your dependent variable is:
       • Categorical / Nominal
         • Use a Chi-Square
       • Continuous / Interval
         • Test used depends on how many independent variables there are
           • Only 1 IV
             • with only 2 levels
               • Use a t-test
                 • Between-subjects design
                   • Use an independent samples t-test
                 • Within-subjects design
                   • Use a paired samples t-test
             • with more than 2 levels
               • Use a one-way ANOVA
                 • Between-subjects design
                   • Use a one-way ANOVA
                 • Within-subjects design
                   • Use a repeated-measures ANOVA
           • More than 1 IV
             • Between-subjects design
               • Use a Factorial ANOVA
             • Within-subjects design
               • Use a repeated-measures ANOVA
             • Mixed-subjects design
               • Use a repeated-measures ANOVA
   • Continuous / Interval
     • and if your dependent variable is:
       • Categorical / Nominal
         • Use a logistic regression
       • Continuous / Interval
         • Test used depends on how many independent variables there are
           • Only 1 IV
             • Use a correlation
           • More than 1 IV
             • Use a regression
